- Bottomless Tokens
Bottomless Tokens allow riders to easily custom tune their RockShox fork’s air-spring performance to best match their own riding style and suspension preference. Adding the easy-to-install Bottomless Tokens changes the air-spring curve to resist bottom-out after a big hit, giving aggressive riders the power to attack the trail harder. Removing Bottomless Tokens makes the air-spring curve more linear, enhancing suspension feel for certain types of terrain or trail condition and ensuring riders who are less front-end aggressive benefit from 100 percent of their fork’s travel.
- Black bottomless tokens are compatible with the following Solo Air forks: RS-1 SID, Reba, Bluto, Revelation.
- Grey bottomless tokens are compatible with the following Solo Air forks: Pike, Lyrik, Yari, Pike DJ, BoXXer.
- Dark red bottomless tokens are compatible with the following Dual Position Air forks: Pike, Lyrik, Yari.
- Dig Valve
RockShox has redesigned the rebound piston to accommodate the Dig Valve, which provides the optimal level of control for both low and high speed compression, carefully controlling the oil flow to provide the rider with the right amount of support and impact absorption. The piston redesign allows the use of Rapid Recovery, a rebound tune that allows the shock to recover faster between consecutive bumps, for greater traction and a more controlled ride.
- Maxle Stealth
Who knew we could make a thru axle disappear? The new Maxle Stealth offers a light, low profile alternative to Maxle Lite and Maxle Ultimate.
- Motion Control DNA
Who doesn’t want more? As a mountain biker, more might mean more rocks, roots, and descents. More also could mean switchbacks, single tracks and steep ascents. The various configurations of Mission Control DNA were designed for those who want more out of their ride, and need more out of their suspension.
For the different riding styles there are four models of Motion Control DNA with Dual Flow rebound (exclusively available in SID and Revelation): XX, RCT3, RTL and RL.
XX - Designed for riders looking for more efficiency. The XX Motion Control DNA damper features RockShox’s XLoc hydraulic remote lockout for the lightest, most ergonomic go-fast solution.
RCT3 – Designed for riders looking for more bump gobbling performance. The new RCT3 damper features three distinct knob positions – Open, Threshold and Lock. The rider is able to quickly and easily access these three modes to manipulate damping performance for specific terrain:
- Open for bump-gobbling performance
- Threshold for efficiency and moderate bump compliance
- Lock for ultimate pedaling efficiency
In addition to its three distinct modes, RCT3 features an independent adjustment of low speed compression.
RLT – Designed for riders who are looking for more stable ride. Featuring the adjustments of Motion Control – compression-to-lock with adjustable threshold updated with a Motion Control DNA spring tube and refined Dual Flow rebound.
RL – For riders looking for a more simple approach to suspension set up. The Motion Control DNA spring tube and refined Dual Flow rebound mated to compression-to-lock adjustability with a factory set threshold.
- Power Bulge™
When you need your forearms to be stronger for more control, you bulk them up in the gym. When you need more durability from your fork, bulk them up with our Power Bulge. Other companies just increase the stanchion size adding extra weight. Power Bulge simply reinforces the lower leg to allow for an oversized bushing, increasing stiffness and maximizing your ride. Plus, it’s called Power Bulge.
- Rapid Recovery™
Who doesn't want more available wheel travel for successive hits? The Rapid Recovery System allows the shock to recovery faster between consecutive bumps, letting the wheel track the ground with greater precision. This more active suspension system, doesn’t pack up and enables the bike to ride in a higher and softer part of the spring rate. Rapid Recovery gives the rider access to more available wheel travel, bump after bump, to achieve a smoother and more controlled ride.
- Solo Air™
Solo Air is like a Buddhist monk. Its enlightened design lets you add air to your forks through a single Schrader valve, filling both the positive and negative air spring chambers simultaneously. So they’re always in perfect equilibrium, like Yin and Yang. Giving you a plush, predictable ride you can set up in seconds, with the lightest weight air spring on the market.
